#     Merge tag 'kbuild-v5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
#     
#     Pull Kbuild updates from Masahiro Yamada:
#     
#      - remove unneeded asm headers from hexagon, ia64
#     
#      - add 'dir-pkg' target, which works like 'tar-pkg' but skips archiving
#     
#      - add 'helpnewconfig' target, which shows help for new CONFIG options
#     
#      - support 'make nsdeps' for external modules
#     
#      - make rebuilds faster by deleting $(wildcard $^) checks
#     
#      - remove compile tests for kernel-space headers
#     
#      - refactor modpost to simplify modversion handling
#     
#      - make single target builds faster
#     
#      - optimize and clean up scripts/kallsyms.c
#     
#      - refactor various Makefiles and scripts
#
